Report on Selected Standardization Activities of the IEEE BASC and of the ATM Forum

This document describes the standardization activities which were performed during the first year period of the joint project named ﲁ Standardization and Research Project on an ATM/B-ISDN Switching Fabric System that is being jointly performed by Protocol Engineering Center (PEC) of Electronics and Telecommunications Research Institute (ETRI), Institute for Systems Research (ISR) of the University of Maryland at College Park (UMCP) and Modacom Co., Ltd. These standardization activities are related to the IEEE Bus Architecture Standards Committee (BASC) meetings and ATM Forum Meetings. This document also provides the general information about the IEEE Standards meetings and ATM Forum Standards meetings.<P

ATM/LAN Access Switch (ALAX): System Architecture

This document contains the hardware information for the ATM LAN Access Switch (ALAX) that was done as a collaborative research and development effort by the Institute for Systems Research at the University of Maryland, College Park, Protocol Engineering Center in Electronics and Telecommunications Research Institute, and Modacom Co., Ltd. of Korea.<P

ALAX- A P1355-Based Architecture for An ATM LAN Access Switch, with Application to ATM Onboard Switching

We draw attention to the new IEEE P1355 Standard for Heterogeneous InterConnect as a possible platform to support several onboard processing functions, including onboard communications and onboard ATM switching. The main features of IEEE P1355 are illustrated through a discussion of the basic principles and protocol architecture of ALAX, the ATM LAN Access Switch, currently under design in the Laboratory for Advanced Switching Technologies at the University of Maryland, College Park

OPNET Simulation Model of the ALAX

When this project wsa undertaken, the ALAX system was designed but was not built yet. Because it was too complicated for us to easily predict the detailed behavior of the system before we built it, we decided to use the OPNET simulation to evaluate the ALAX system before it was built. The performance of the ALAX could be predicted by analyzing the results of the OPNET simulation, and the optimal architecture of the ALAX developed by devising the proper number of transputers and the proper packet buffer size of the ALAX system.<P

ATM LAN Access Switch (ALAX): Protocol Architecture (LAN Emulation Version)

This document describes the protocol architecture of the LAN Emulation Version of the ATM LAN Access Switch (ALAX). The main function of the ALAX is to provide an interface between legacy LAN and ATM world giving network managers the option of gradually integrating ATM technology into their existing networks. To provide this functionality to the ALAX system, we decided to implement two versions of the ALAX system. One is the LAN emulation version and the other is the Multi Protocol Over ATM version. The most important design characteristics of the ALAX is the adoption of the IEEE P1355 Standard for Heterogeneous Inter Connect (HIC)[1] as the data communication paths within the ALAX switching system. This makes it possible to design the PC- based parallel architectured high performance switching system in conformance with emerging open technologies and related standards. The protocols needed within the LAN Emulation version of the ALAX include LAN Emulation, Bridging Relay function, P1355, MAC Mapping Layer (MML), MAC, LAN Physical, AAL5, ATM and ATM Physical Layer. Some other protocols needed in the ALAX include the ATM signaling which is defined in ATM Forum UNI 3.0[2] , Network Management (SNMP or CMIP)[3], Graphic User Interface and some main control functions of the ALAX. The details of all these protocols, the relationship among these protocols and the implementations of these protocols are described in this document.<P
